Astronomers utilizing NASA’s James Webb Space Telescope (JWST) have uncovered a new class of galaxies that defy traditional ...

Observations of ultra-massive galaxies, each containing more than 100 billion stars, show that less than 2 billion years ...

An inexplicably hot, fast-growing cluster of galaxies in the early universe has scientists questioning theories of galactic ...

Webb reveals a bridge of stars linking two nearby dwarf galaxies, offering a look at how gravity reshapes galaxies and sparks ...

Using data from the James Webb Space Telescope, astronomers traced how Milky Way–like galaxies formed and changed over time.

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

Gas cloud collisions during galaxy mergers compress interstellar material, triggering new star formation, as observed in interacting systems studied by NASA and reported by Universe Today.

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

Astronomers know that most galaxies house supermassive black holes in their centers, from the largest galaxies down to small dwarfs. They also know that when supermassive black holes are actively ...

Images taken using the Hubble Space Telescope have given astronomers clues about the formation and growth of the first galaxies, suggesting that early star formation happened in violent bursts. A team ...

An international team of astronomers has uncovered multiple evolutionary paths for the universe's most massive galaxies. Observations of ultramassive galaxies, each containing more than 100 billion ...
